If two parallel lines are intersected by a transversal, what is the relationship between the interior angles on the same side of the transversal?
- They are equal.
- They are complementary (add up to 90 degrees).
- They are supplementary (add up to 180 degrees).
- They are vertically opposite.
Show answer
Answer: C. They are supplementary (add up to 180 degrees).
When a transversal intersects two parallel lines, the interior angles on the same side of the transversal are consecutive interior angles. These angles are supplementary, meaning their sum is always 180 degrees.
What is the name of a triangle with all three sides of different lengths?
- Equilateral triangle
- Isosceles triangle
- Scalene triangle
- Right-angled triangle
Show answer
Answer: C. Scalene triangle
A scalene triangle is a triangle in which all three sides have different lengths, and all three angles have different measures.
What is the area of a square with a side length of 5 cm?
- 10 sq cm
- 20 sq cm
- 25 sq cm
- 30 sq cm
Show answer
Answer: C. 25 sq cm
The area of a square is calculated by Side × Side. Area = 5 cm × 5 cm = 25 sq cm.
An angle less than 90 degrees is called:
- Acute angle
- Right angle
- Obtuse angle
- Straight angle
Show answer
Answer: A. Acute angle
An acute angle is an angle that measures less than 90 degrees.
Which shape has four sides of equal length but not necessarily four right angles?
- Square
- Rectangle
- Rhombus
- Parallelogram
Show answer
Answer: C. Rhombus
A rhombus is a quadrilateral with all four sides equal in length. Its angles are not necessarily right angles, which distinguishes it from a square.
